文档介绍：摘要
软弱膨胀土地基是一种比较特殊的地基。当利用这种土作为建筑物地基时,必须采取必要的处理措施,以消除土的膨胀潜势。处理措施一般分为深层和浅层处理,本文通过工程实例,分析了不同建(构)筑物在相同的地质条件下的几种处理方法,重点阐述了真空预压联合堆载法+强夯法加固软土地基的施工工艺过程及真空预压联合堆载法施工难点的控制措施。

Abstract
Weak expansion of the land base is a special foundation. When the use of this land as a building foundation, we must take the necessary measures to deal with in order to eliminate the expansion of soil Potential. Treatment measures are generally deep and shallow sub-processing, this paper engineering examples, analysis of different construction (structures) in the same plex geological conditions, several treatment methods.
